Answer: 4896 ways

Step-by-step explanation:

This is a permutatiom problem, since order does matter.

18P3 = 18!/(18-3)!

=18 × 17 ×16 ×15! / 15!

=18×17×16

=4896

What is the equation of the line in y=mx+b format? BRAINLIST WILL BE REWARDED
harkovskaia [24]

Answer:

y = 2/5x - 1

Step-by-step explanation:

There are a couple of different ways to figure this out, but since you have a graph, the fastest way is to count the slope, or m in the formula, by counting the rise (units up) over run (units to the right), which is 2/5. Then, find the value of b by finding the y-intercept on the graph, or -1.
